How is the project built?  When I type `make` inside Documentation/, I
want documentation to be built.  When I want a toplevel-build, I use a
custom git-make function (which does a cd before calling make).

*scratches head*

  cd Documentation; git blame ../Makefile

Isn't this how pathspecs are specified everywhere?

  cd Documentation; git log ../Makefile
  cd Documentation; git log -L0,10:../Makefile

What is the difference between "concrete path" and "pathspec"?
